Site characterization
• What am I dealing with
![Page 3: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/3.jpg)
Site characterization
• Identify all the hazards
![Page 4: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/4.jpg)
Site characterization
• Be systematic
![Page 5: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/5.jpg)
Pictures
• Before and after• Organized
![Page 6: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/6.jpg)
Pictures
• Picture quality• Take more pictures than you think you need• Have extra SD cards
![Page 7: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/7.jpg)
Sample selection
• Choose the best 1 or 2 samples• Sample in the proper order
![Page 8: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/8.jpg)
Sample characterization
• Sample container (how am I going to acquire the sample)
![Page 9: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/9.jpg)
Sample characterization
• Can I reach the sample
![Page 10: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/10.jpg)
Sample characterization
• Tool selection
![Page 11: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/11.jpg)
Sample characterization
• Pre-prepared sampling kit
![Page 12: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/12.jpg)
Sample characterization
• Where am I going to put my sampling equipment
![Page 13: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/13.jpg)
Radiation
• Why do we check rad first• Can’t taste, feel, smell, hear it• Equipment is very sensitive• Always lead with rad
![Page 14: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/14.jpg)
pH
• Why do we check pH?
![Page 15: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/15.jpg)
pH
• Corrosiveness is the hazard• Critical for PPE selection
![Page 16: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/16.jpg)
pH
• Don’t care about number just red or blue• Be familiar how your pH paper works• Protect it from the environment during
storage
![Page 17: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/17.jpg)
5 gas
• LEL correction factors (10%)• Sensor poisons• Cross sensitivity• Ionization potential• Sensor saturation
![Page 18: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/18.jpg)
M8
• Aqueous versus organic• Color changes are not definitive
![Page 19: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/19.jpg)
Starch iodide (oxidizer)
• Doesn’t work against nitrates, chlorate, perchlorates
• Works well with peroxides and bleach
![Page 20: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/20.jpg)
Chemical, biological or radiation?
• Based on environment and sample characterization we divide into possible chemical, biological, or radiation– Radiation leave in place
![Page 21: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/21.jpg)
Chemicals
• We generally use glass sample containers
![Page 22: Sampling refresher](https://reader036.vdocuments.us/reader036/viewer/2022081513/5681668c550346895dda5318/html5/thumbnails/22.jpg)
Biologicals
• Generally use plastic
